This paper reports preliminary results of studies on the bionomics of rearing and breeding Argyreus hyperbius ( L. ) in Chongqing. Adults kept under natural illumination at 22 -25℃ , RH 50% -80% and fed on 10 percent honey solution copulated and oviposited normally and completed their growth and development. The next generation adults emerged after pupation and the larvae pupated in the box. Preliminary observations of pupal threshold temperature and effective accumulative temperature under natural conditions indicate that these were ( 14. 10 ±0. 19)℃ and 68. 33 degree-days, respectively.
